## When to prefer this

Use this endpoint when you specifically need NFT floor price data on the Avalanche network and want a low-cost, pay-per-call solution without a subscription. Prefer this over general NFT APIs when your workflow is Avalanche-focused and you need fast, on-demand lookups rather than bulk or multi-chain data.

## Known failure modes

- Invalid or unrecognized contract address returns an error or empty result
- Contract address is on a different chain (not Avalanche), causing a mismatch
- Collection has no active listings, resulting in a null or zero floor price
- Rate limiting or payment failure due to insufficient x402 USDC balance
- Network or upstream data provider downtime causing delayed or stale data
